I don't blame Jamie's attitude on his respect of his equipment and his $30000 Lathe. 2 mins of wiping his arse instead of leaving a huge pile of shavings and detritus over the Lathe and expecting someone else to do it is a complete antithesis of his actions on Tested!!!

This is awesome! Thanks for uploading

This is incredible! Congrats and thanks for all the hard work, it looks amazing even now. I can't wait to see what it looks like completed.

I wonder why at 1:52 both wander and agro are in field together, and it doesn’t look like Malus arena either, unless it’s just a older version of it. Who the hell was supposed to be the last colossus.

😂

My spice cure remedies is egg yolks..

For the big cannon, it seems the boiling portion is iron, not copper (which has 7 times the heat conductivity!) and the surface is smooth again (the surface is too small). Also, 24 pounds is definitely too much, 2-4 pounds would be better (hollowed ball? smaller barrel width? different ball material) and the chamber size overall seems too small (the water amount too). Also, using boiling water will allow you to just completely fill the chamber with water as you won't be losing any heat by it AND increase the pressure from the steam (since there will be less space and some from not having to heat up the water). So I wouldn't say it's impossible just based on this video.

I remember this show from the 2000s, even in Germany this was a big hit. Great they own steam device works pretty well on the end of the Video. Lol 31:18 Ice Age moment:)

24:26 that was the cannon equivalent of having a giant ass d*ck but only c*m dribble 😅😂🤣

I can't belive they had an ebike with 2 big hub motors in 2006. They started to be popular aroud 2019. I'm curious if they built it themselves.

I NEVER try things from Mythbusters at home ! I ALWAYS go to a friend !

Surely the water has to be heated at the same time as the tank otherwise the sudden ingress of cold water will act in the same way as quenching when tempering metal. So, fill the tank with water, bring both to the required temperature and pressure and the ball will be forced out of the barrel. That is why a canister of water inside a fire will explode with such violence. Archimedes would never be able to attain 1500 degrees. However, if the missile was the lid of the container and the water and chamber were heated at the same time, the pressure would build at a much lower temperature. I'm not a scientist but surely something on these lines is nearer to the capabilities of technology two and a half thousand years ago.

Can you use ice instead of water?

I feel like a second valve, for the water. Along with a more thorough heating method(inside) would ve worked better, whwn like jaime says "idk why this didn't work,", I feel it's just for TV.....Or they've spent too much time on TV and movie, "Special Effects for 30 years" that they forgot reality, lmao.

I said this already but seeing Grant Alive and well hurts the feels bro..... At least he had a productive life and alot of fun on this show!

in this episode, adam & jaime test cardbridge vs sugar cereal, this guys realize an experiment with lab rat, but the rats ate cardbridge previusly ate another rat.

I miss this show

I wonder if their insurance required them to use modern materials for the steam canon.

Did… did Adam coin the term hyper pop nearly 2 decades before?

A friend i my had some mirrors in the garden to provide some extra light for some plants in his garden, was quite shocking to see some of his wood of his veranda got scorched/charred (distance between mirrors and wood is about 4m/13ft). So Archimedes his solar death ray might not be a bust at all.

Hot chocolate?

Even if the cereal box had more calories than sugary cereals, so what? You can't eat paper. Paper is mostly cellulose. You can't digest cellulose, so why would you care?

Bunch a geek with equipment ❤

## TIME HAS RUN OUT !! John 3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. Don't ignore this message... REPENT NOW !! TRUST that God raised Him from the dead !! By FAITH accept JESUS's blood alone as payment for your sins unto Salvation, to escape what's about to happen !!

Man, there's no way that cereal has 9 calories in just 1 gram. It would've had to be made out of 100% pure fat, which is not. It's likely like 80% carbs by mass, with some artificial flavors and colorants. At maximum it has maybe 6-7 calories, which is a very high overestimate. It just shows the calorimeter wasn't accurate enough, and cardboard caloric data by extension also wasn't accurate.

How about a pre heated steel ingot that is interchangeable via a breech.

Jamie looks like a walrus.

Man Adam's predictions in percent, the don't try this at home warning... It's been 15 years since I saw an episode. What a blast from the past. I enjoyed it tremendously. Thank you.

That famous fight in the back, where somebody in the MB staff got severly damaged . 21:47

a sealed cannister with water inside the barrel that ruptures at a certain pressure could do the trick. Once the pressure is released, every last bit of water that was kept liquid before by pressure flashes instantly into steam

Just another comment about how gasses compresses, and how much more steam volume they need to create gaseous pressure in that cannon volume.

Silly sods. You need a burst valve. Greeks could have done that. Steam pressure is built in a chamber until it breaks a membrane leading to the barrel. Tube diameters are important too. Gas velocity v gas volume etc. That rig had no chance. The ball could have been the membrane...

That wasn't busted they didn't do it right

The funny part about watching this show retroactively: Mr. Hyneman did quite literally all of the engineering, until the build crew was added in, in which Hyneman and Imahara did vast majority of the engineering work. Adam is here for mostly comic relief, and according to the people on the set he's often intolerable to be around, so he's not friends with anyone in this show, least of all Jamie. Any time Adam basically did any work building or worse, engineering anything it's just a lot of loud cursing and blaming everything and everyone but his own mistakes. Jamie basically summarizes the entire experience of all the seasons at around 4:00 here. The only reason he's kept in is because the producers insist he's entertaining.

It was a sad day when they changed the format to mostly be about guns, crashes and explosions.

21:47 guy in the background made me lol for some reason.

solid water????

@21:47 did anyone else notice that?

It's strange to me that they measured nutrition by calories. A piece of vegetables will have way less calories than a piece of chocolate cake, but way more nutrients.

Eppisode disapointment

26:20 amazing

that does not mean that it could not have been done in ancient times... the pyramids spring to mind... could we do it today?

It was obvious from the start that it needed a pressure release valve.

🇺🇸Ans 😂😂😂 Try HOT Water

Haha, didn't The Great Myth Busters know the trick to burn sugar? It is cigar ash! Believe it or not cigar ash is the classic example of a kathalysator. When you put some of it on a lump of sugar, you will see FLAMES when you try to light it. Without the ash, it just melts. Exactly what Adam shows here. Smoke a cigar, collect the ash in a nice clean tray, put a bit on the candy and you'll see the candy burn. Tadaah! Don't Adam KNOW that?! They should know...

39:55 lol

RIP Grant

HOLD ON THERE PEOPLE! Jamie lifted the cannon ball out of a depression, meaning it did not roll there it LANDED there. How did they miss this?

The steam cannon would work with a completely different design. To produce sufficient energy the size of your heated surfaces is going to be massive which makes this design hopeless. Now, if you go back to the pneumatic chicken cannon you just might get the results you want. Build a flash boiler instead of using a compressor and store the steam from the flash boiler in a vessel. When you have a couple hundred pounds of pressure on hand in sufficient volume, open a large valve that closes off a ducting to the barrel and you have a steam cannon that might actually work. Your retention vessel should be sized to contain 1.5 to 2 times the total volume of your barrel. That will ensure your projectile will reach the end of the barrel under full pressure.

Leonardo's notes = backward Italian scribbles... Nice one Adam, dumbing it down for your audience.
